Jailbroke on 3GS bb5.14 IOS 4.12but question on Ultrasnow

The day before announcement on nov 29th
About jb and unlock for 3GS I thought I saw
A post for jb and unlock for my phone, and I'm pretty
Sure that I used Ultrasnow 1.1, however, I never
Did test the unlock.....so when I saw the
29th announcement, went to Cydia and I
Think I replaced Ultrasnow 1.1 with 1.2 upgrade.
I didn't re jailbreak, and for now want to
Stay with iOS 4.12. My basement still shows
Up as 5.14 and I still haven't yet found another
Carrier sim to try the unlock.
Judging from my brief description do
You think I am ok with my above procedure?
I know that with the nov 29th release,
I didn't want to go to iOS 4.2 and deal with
The 6.5 issue. If you figure that I am
Not ok in what I did could you recommend
What jb and unlock procedure to take
For bb 5.14 iOS 4.12 on 3gS? Thanks
I want to stay one step behind in my upgrade
Just to have my wife with an unlocked phone
